JavaScript: Get an array of given n random integers in the specified range

JavaScript fundamental (ES6 Syntax): Exercise-35 with Solution

Write a JavaScript program to get an array of given n random integers in the specified range.

• Use Array.from() to create an empty array of the specific length.
• Use Math.random() to generate random numbers and map them to the desired range, using Math.floor() to make them integers.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 
const random_intArray_In_Range = (min, max, n = 1) =>
  Array.from({ length: n }, () => Math.floor(Math.random() * (max - min + 1)) + min);
console.log(random_intArray_In_Range(1, 20, 10));
console.log(random_intArray_In_Range(-10, 10, 5));

Sample Output:

[10,5,17,4,19,5,4,6,9,2]
[7,-6,2,-9,-2]
